Humans also create value through ethical restraint, the ability to recognize when not to cut corners, when to delay, and when to prioritize patient safety or scientific rigor over speed. That human ...

The Q-matrix serves as a bridge that links items and attributes, and its accuracy affects the results of cognitive diagnosis. Inaccuracy of the Q-matrix are a common issue frequently encountered in ...

M-M.E.S.S. provides low-rank solvers for large-scale symmetric matrix equations with sparse or sparse + low-rank coefficients. The main focus is on differential and algebraic Riccati equations ...

This survey provides a comprehensive overview of the solutions to the matrix equation AXB=C over real numbers, complex numbers, quaternions, dual quaternions, dual split quaternions, and dual ...

Abstract: Discrete coupled Riccati matrix equations, which play an important role in the analysis and design of discrete-time Markov jump systems of control theory, have been studied extensively. In ...

The solvability conditions and the general solution of the dual matrix equation PX+YG=Q under the linear constraints AX=C and YB=D are deduced by applying the generalized inverse. Furthermore, the ...
